I've done this before. For a small change in a .c file, it takes less than a couple of minutes in a not-so-fast computer. It only has to recompile that .c file, do a partial link of the subsystem, do a final link of the whole kernel, and a few other auxiliary processing steps. It takes more time to reboot the machine or VM with the new kernel.
Even compiling the kernel from scratch is fast. Looking at a Phoronix benchmark (https://openbenchmarking.org/showdown/pts/build-linux-kernel), it takes less than 15 minutes on all systems tested. Some systems can compile the whole kernel from scratch in less than half a minute.
